FLANGING-HEAD.

Specification of Letters Patent.

Patented Aug. 2H, 1916.

Application filed July 23, 1910. Serial No. 573,428.

To all whom it may concern:

Be it known that I, JESSE E. ABRAMs, a citizen of the United States, residingl at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Flanging-Heads, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in Hanging heads, and more especially a Hanging head which includes a die that is adapted to operate upon a can body for turning a Hange at the outer end thereof.

An object of the invention is to provide a Hanging head with a die which is yieldingly supported, and which operates to strip the can body from the Hanging head.

A. further object of the invention isY to provide a limiting ring in connection with a Hanging die, which ring may be readily detached and a new one substituted therefor.

These and otherobjects will in part be obvious, and will in part be hereinafter more fully disclosed.

In the drawings which show by way of illustration one embodiment of the inven- Ation,-Figure 1 is a section ofa Hanging head embodying my improvements; Fig. 2 is a similar View, showing the die in position for the completing of the Hanging operation; Fig. 3 is a view of a head such as shown in Figs. 1 and 2, and showing the first operation upon the can body; Fig. 4 is a view of a slightly different form of die for performing the second operation upon a can body; Fig. 5 shows a can body having a preliminary Hange or curl formed thereon; and Fig. G shows a can body having a finished flange formed thereon.

My improved Hanging head is adapted to be used in connection with any desired operating means, and, therefore, I have merely shown herein a support 1 in which the head may be reciprocated. The Hanging head is attached to a stem 2, which slides in the support 1, and a roller 2 carried by the stem engages a cam 4, which will reciprocate the Hanging head into and out of the can body or other article being Hanged.

The Hanging head consists ofA a die 5, which is threaded at 6 on to a sleeve 7 that fits within a recess 8 formed in the stem 2. A spring 9 is interposed between the end of -of the can.

an enlarged head for limiting the outward movement of the sleeve 7, under the inHuence of the spring 9. Said sleeve is also provided with a shoulder 11, which engages the end of the stem when therdie is forced inwardly, and thus limits the inward movement of the die.

A cap 12 is threaded on to the end of the stem 2, and has 4a seat formed in its outer face to receive a limiting ring 13, which cooperates with the die 5. A collar 14 is threaded on to the cap 12, and has an inwardly extending flange which engages a rib on the outer face of the ring 13 and locks the same on its seat on the cap 12. The ring 13 is preferably formed of hardened steel` and is shaped so that the die 5 slides back and forth in the ring.

In the operation of my device, the can body C is placed on a rest or support 15, and the Hanging head is moved into the can body. The die first engages the can body. The spring 9 will yield, allowing the die to move inwardly, and the edge of the can body is gradually expanded or turned voutwardly into a Hange. The shoulder 11 on the sleeve 7 engages the end of the stem, and the die is now positively forced into the can body. rlhe edge of the can as it is turned will come into contact with the limiting ring 13, which assists in forming the Hange. rlhe raw edge of the metal is brought into wearing contact with the ring 13, which is of hardened steel. If this ring wears, it may be readily removed and quickly reversed and again attached to the Hanging head, which will bring a different wearing surface into contact with the edge Then again, the ring may be quickly replaced by another one, when desired.

It will be seen, therefore, that I have provided a Hanging head in which the first action of the die is yielding, and the later action is positive. I have also provided a Hanging head wherein the wearing surface may be made of hardened steel which cannot only be quickly reversed so as to bring a different surface into contact with the can body, but which can be readily replaced Without destroying the entire H-anging head. Then again-by making the die yielding as soon as the Hange is turned and the Hanging `head is moved away from the can body, the

die will temporarily remain in the can body through' the force of the spring acting on the die, and thus cause the can body to be stripped from the Hanging head.

In order to turn a flange which is substantially at right angles to the can body, I preferably perform two operations upon the can body. In Fig. 3 I have shown a Hanging head 16, which will operate to turn a preliminary Hange 1,7 on the can body, as clearly shown in Fig. 5. In Fig. 4 I have shown a Hanging head 18, in which the die f is cut away so as to receive the can body with a preliminary flange, and turn the same iFnto a finished Hange 19, as clearly shown in I preferablyuse these Hanging heads in i different machines and feed the can bodies first to one machine and then to the other. This gradual turning of the Hange allows the metal to How, and prevents the opening of the side seam or the splitting of the metal. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

2. A Hanging head including in combination a stem, a cap carried thereby, a limiting ring of hardened steel seated on said cap a collar for holding said ring on its seat, a die located within said ring and movable relative thereto, a sleeve connected to said die and engaging a recess formed in said stem, a limiting bolt passing through said sleeve for limiting the outward movement of said die, a spring encircling said bolt for forcing the die outwardly, and a shoulder formed on said sleeve for limiting the inward movement of said die.

3. A Hanging head including in combination, a stem, a cap carried thereby, a limiting ring mounted on said cap, means for detachably. holding said ring on said cap, a die located centrally of said limiting ring, and means for yieldingly supporting said die, whereby the same may be moved relative to said limiting ring. e

4. A Hanging head including in combination, alstem, a cap carried thereby, a limiting ring seated on said cap, a collar for detachably securing said ring to said cap, a die mounted to reciprocate within said ring, means for yieldingly supporting said die,

'means for limiting the outward movement of said die, and means for limiting the inward movement of said die.

In testimony whereof I affix my signature, in presence of two witnesses.
